Ear Trainer — Sing the Note You Hear
Hides the "You sing" note while the target is playing, so a tone leaking from your speakers into the mic isn't shown as the answer. Detection keeps running — it's just not displayed. Turn this on if you're not using headphones.

Privacy. Microphone audio is processed entirely in your browser and never leaves your device — we do not record, store, or transmit what you sing.
We don't collect anything. No analytics, no cookies, no accounts, no tracking — we have no idea who you are or how you use the app.
We save your settings and practice stats (streaks, total correct) locally in your browser so they're remembered next time. This stays on your device and is never sent anywhere.
Instrument samples are loaded on demand from public CDNs, and the site is served through a hosting/CDN provider. As with any website, those providers may log standard HTTP request metadata (IP address, user agent) at the network level according to their own policies.
Terms. Provided as-is, without warranty of any kind. Free to use for personal ear training.
